John Crispin 7c78b4ad9b net: mediatek: move the pending_work struct to the device generic struct
The worker always touches both netdevs. It is ethernet core and not MAC
specific. We only need one worker, which belongs into the ethernets core
struct.

John Crispin 656e705243 net-next: mediatek: add support for MT7623 ethernet
Add ethernet support for MediaTek SoCs from the MT7623 family. These have
dual GMAC. Depending on the exact version, there might be a built-in
Gigabit switch (MT7530). The core does not have the typical DMA ring setup.
Instead there is a linked list that we add descriptors to. There is only
one linked list that both MACs use together. There is a special field
inside the TX descriptors called the VQID. This allows us to assign packets
to different internal queues. By using a separate id for each MAC we are
able to get deterministic results for BQL. Additionally we need to
provide the core with a block of scratch memory that is the same size as
the RX ring and data buffer. This is really needed to make the HW datapath
work. Although the driver does not support this yet, we still need to
assign the memory and tell the core about it for RX to work.
